AXLE-BOX EXTENSION FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 452,539, dated May 19,1891. Application filed December 18, 1890. Serial No. 375,131. (Nomodel.)

T00 whom it may concern:

Be it known that we, WILLIAM B. BEAGLE and WILLIAM C. CLARK, citizens ofthe United States, residing at Sh'elbina, in the county of Shelby andState of Missouri, have invented new and useful Improvements in Axle-BoxExtensions for Vehicles, of which the following is a specification.

In vehicles having wheels with wooden hubs the ends of the axle boxes orbushings wear, and to set the nuts up it is usual to cut the threads andshoulders of the axle-spindles farther back and sometimes to cut offportions of the spindles, which necessitates the employment ofaxle-cutters. The cutting of the axle-spindles is expensive andtroublesome and therefore objectionable.

The object of our invention is to provide novel, simple, efficien t, andeconomical means for renewing the end of an axle box or bush when undulyWorn, whereby the cutting of the axle-spindle and the expense incidentthereto are avoided.

The invention also has for its obj ect to provide a novel device whichis complete in itself and susceptible of being applied at will to awooden hub for forming an extension to the worn end of an axle box orbush, which extension accurately fits and turns upon the axle-spindle,as though an integral part of the box or bush.

To accomplish all these objects our invention involves the features ofconstruction hereinafter described and claimed, reference being made tothe accompanying drawings, in which- Figure l is a detail sectional viewof a wheel-hub and axle-spindle, showing our invention applied thereto;Fig. 2 is a detail perspective view of theimproved device for renewingor extending a worn box or bush. Fig. 3 is a side view. Fig. at is asectional view of the same.

In order to enable those skilled in the art to make and use ourinvention, we will now de scribe the same in detail, referring to thedrawings, wherein- The numeral 1 indicates a wooden wheelhub; 2, itsmetallic axle box or bush; 3, the

axle-spindle, and at the axle-nut for retaining the wheel on thespindle. The constant rotation of the'axle box or bush against astationary part wears the ends of the box or bush, and the wheel-hubsoon becomes loose on the spindle. To compensate for wear and tightenthe hub on the spindle, loose washers are used; but these fall to theground every time the wheel is removed for lubricating the spindle orother purposes.

The continued wear of the box or bush has heretofore rendered itnecessary to cut the threads and the shoulder of the axle farther backto permit the nut to be set up, and sometimes it is essential to cutoffor remove a part of the spindle, all of which is objectionable, in thataxle-cutters are required and the work is expensive and troublesome. Toavoid the objections stated, we provide an annulus or ring 5, havingconcentric inner and outer surfaces 6 and 7 and parallel opposite edges8 and 9. This ring is provided with a series of pointed spurs or prongs10, which extend from the exterior surface 7 in such manner as to permitthe edge 8 of the ring to rest squarely against the worn end of the axlebox or bush 2, while the spurs or prongs 10 enter the wood part of thehub at a point outside of the box or bushf The ring and spurs or ron sare referabl castintegral of malle P a able iron; but obviously they canbe cast of any other metal suitable for the conditions required. Thering is substantially square in cross-section, and whether the spurs orprongs be cast integral with or are attached to the ring they must be soarranged relatively to the periphery of the ring that the inner edge 8thereof can rest against the worn end of the axle box or bush, while thespurs or prongs can penetrate the hub at points outside the box or bushin such manner that the ring constitutes an extension to the box orbush, which is flush with the internal surface of the latter and bearsupon the axlespindle, the same as though the ring were an integral partof the box or brush.

In applying the ring to form an extension of the box or bush such ringis placed upon the end of the spindle and is then driveninto place, sothat its spurs or prongs penetrate the wooden part of the hub outsidethe box or bush, whereby the ring is permanently attached, and thereforeremains as a fixed part of the hub, which prevents its falling off whenthe wheel is removed for lubricating or other purposes.

\Ve purpose manufacturing these box-extension rings of different sizesto correspond with standard gages of axlespindles and axle boxes orbushes, and while the rings are preferably cast of malleable iron we donot confine ourselves thereto.

lVe have exhibited the ring as provided with three spurs or prongs; butobviously a greater or less number can be employed. These spurs orprongs are tapering and sharp-pointed to easily penetrate the woodenpart of the hub, and the rings are in diameter and thickness coequalwith the diameter and thickness of the boxes or bushes to which they areto be applied.
